Forest insects and diseases in Canada are typically classified into three broad categories: Native: Indigenous species that have existed in Canada for thousands of years. However, very few succeed in establishing a home here because of Canada’s generally effective natural barriers, such as climate, a vast land mass and topography.

Invasive species can also affect species behaviour and ecosystem function. Of the species that manage to establish themselves in Canada, only a few can be termed invasive alien species or pests because of the extensive damage they cause and threats they pose to the integrity of our forest ecosystems. Invasive species, specifically invasive plants, can interfere with forest regeneration and productivity through direct competition with tree seedlings, resulting in reduced density and slowed growth rate of tree saplings. The risk of introducing alien species (insects and diseases) will increase in Canada over the next few years for various reasons: How do alien insects and diseases get into Canada?

Examples are spruce budworms and mountain pine beetle. In ecological terms, the pests can cause significant damage to indigenous trees and plants that lack natural defenses against these invaders. Once established, they can permanently alter the soil structure, disrupt native plant communities, reduce dependent wildlife populations, and impact long-term forest productivity. In short, the entry points for these unwanted guests are often the entry points of international trade. In economic terms, alien pests have a considerable impact. Invasive species can cause great economic and environmental harm to the new area. One particular new arrival in Canada is the emerald ash borer. But solely in terms of timber losses, we know that forest pests destroy about 400,000 ha of forest every year in Canada, which is slightly less than half of the 930,000 ha harvested annually by the forest industry.

Invasive, nonnative plant species have been a concern of land managers within the temperate and boreal coniferous forest eco-region for nearly a century. They slow down growth, kill trees and plants, and reduce the quality of lumber and harvests. These species are termed invasive if they are able to modify indigenous ecosystems either as pests or competitors. In Quebec alone, 600,000 elm trees were destroyed or chopped down between 1945 and 1965 because of this disease. This invasive species wiped out forest and industry in just a few decades. Consequently, they change the internal dynamics and possibly rupture the characteristic equilibrium of ecosystems, because the damage they cause adds to various natural or human disturbances.
